Forskningsöversikt (refereegranskat)abstract
- Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world’s brightest neutron source. As such, it has the potential for a particle physics program with a unique reach and which is complementary to that available at other facilities. This paper describes proposed particle physics activities for the ESS. These encompass the exploitation of both the neutrons and neutrinos produced at the ESS for high precision (sensitivity) measurements (searches).

- In this manuscript a number of general inequalities for isotonic subadditive functionals on a set of positive mappings are proved and applied. In particular, it is pointed out that these inequalities both unify and generalize some general forms of the Holder, Popoviciu, Minkowski, Bellman and Power mean inequalities. Also some refinements of some of these results are proved.

Who moves and who gains from internal migration in Egypt?: Evidence from two waves of a labor market panel survey

Tidskriftsartikel (refereegranskat)abstract
- In recent decades, Egypt has experienced rapid internal migration movements triggered by urbanization, socioeconomic development, and environmental changes. From a literature perspective, few scholarly studies have empirically examined the drivers and welfare impacts of internal migration in Egypt, despite the increasing recognition of its inextricably links to urban sustainability. The present study utilized data from two waves of an Egyptian Labor Market Panel Survey (ELMPS) conducted in 2012 and 2018 and consisting of 63,909 observations to examine factors that determine internal migration decisions and their subsequent welfare effects. The results of the two-stage Heckman selection model indicate that both the determinants of internal migration decisions and welfare outcomes differ appreciably depending on migration stream as well as the socioeconomic characteristics of the migrants. In particular, females were found to be more likely to migrate from rural to urban areas, lending support to the growing literature on the “feminization of migration” in developing countries. The OLS regression results, after correcting for self-selection, make a strong case for the positive welfare gains from internal migration in Egypt. Specially, we found that the welfare gains for older and female migrants are much higher than other age and gender groups. A comparison of the welfare effects between different migration streams shows that all migratory movements were associated with positive and statistically significant welfare gains, except for rural-to-urban migration that was surprisingly found to be associated with significant welfare loss for the migrants. Urban-to-urban migration was found to have the strongest welfare enhancing effects on all migrant groups. The empirical findings underline a number of research and policy implications for a sustainable management of internal migration in Egypt and other countries with similar internal migration trends.

Revealing the deeper structure of the end-glacial Pärvie fault system in northern Sweden by seismic reflection profiling
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Fault scarps that extend up to 155 km and have offsets of tens of meters at the surface are present in the northern parts of Finland, Norway and Sweden. These fault scarps are inferred to have formed during earthquakes with magnitudes up to 8 at the time of the last deglaciation. The Pärvie fault system represents the largest earthquake so far documented in northern Scandinavia, both in terms of its length and its calculated magnitude. It is also the longest known glacially induced fault in the world. Present-day microearthquakes occur along the length of the fault scarp on the eastern side of the scarp, in general agreement with an east dipping main fault. In the central section of the fault, where there is a number of subsidiary faults east of the main fault, it has been unclear how the earthquakes relate to the faults mapped at the surface. A seismic profile across the Pärvie Fault system acquired in 2007, with a mechanical hammer as a source, showed a good correlation between the surface mapped faults and moderate to steeply dipping reflectors. The most pronounced reflector could be mapped to about 3 km depth. In an attempt to map the fault system to deeper levels, a new 22 km long 2-D seismic profile which followed the 2007 line was acquired in June 2014. For deeper penetration an explosive source with a maximum charge size of 8.34 kg in 20 m deep shot holes was used. Reflectors can now be traced to deeper levels with the main 65◦ east dipping fault interpreted as a weakly reflective structure. As in the previous profile, there is a pronounced strongly reflective 60◦ west dipping structure present to the east of the main fault that can now be mapped to about 8 km depth. Extrapolations of the main and subsidiary faults converge at a depth of about 11.5 km where current earthquake activity is concentrated, suggesting their intersection has created favorable conditions for seismic stress release. Based on the present and previous seismic reflection data, potential locations for future boreholes for drilling into the fault system are proposed.

Stability of a quasi-local positive mass theorem for graphical hypersurfaces of Euclidean space

Tidskriftsartikel (refereegranskat)abstract
- We present a quasi-local version of the stability of the positive mass theorem. We work with the Brown–York quasi-local mass as it possesses positivity and rigidity properties, and therefore the stability of this rigidity statement can be studied. Specifically, we ask if the Brown–York mass of the boundary of some compact manifold is close to zero, must the manifold be close to a Euclidean domain in some sense?Here we consider a class of compact -manifolds with boundary that can be realized as graphs in , and establish the following. If the Brown–York mass of the boundary of such a compact manifold is small, then the manifold is close to a Euclidean hyperplane with respect to the Federer–Fleming flat distance.

A Federated Interactive Learning IoT-Based Health Monitoring Platform

- Remote health monitoring is a trend for better health management which necessitates the need for secure monitoring and privacy-preservation of patient data. Moreover, accurate and continuous monitoring of personal health status may require expert validation in an active learning strategy. As a result, this paper proposes a Federated Interactive Learning IoT-based Health Monitoring Platform (FIL-IoT-HMP) which incorporates multi-expert feedback as ‘Human-in-the-loop’ in an active learning strategy in order to improve the clients’ Machine Learning (ML) models. The authors have proposed an architecture and conducted an experiment as a proof of concept. Federated learning approach has been preferred in this context given that it strengthens privacy by allowing the global model to be trained while sensitive data is retained at the local edge nodes. Also, each model’s accuracy is improved while privacy and security of data has been upheld.
